31.1 Content Filter Overview

Content filter allows you to block certain web features, such as cookies, and/or block access to
specific web sites. It can also block access to specific categories of web site content. You can
create different content filter policies for different addresses, schedules, users or groups and
content filter profiles. For example, you can configure one policy that blocks John Doe's
access to arts and entertainment web pages during the workday and another policy that lets
him access them after work.
